Green fiscal reforms would contribute to climate change mitigation, increase the economic efficiency of national tax systems and provide additional public revenues. Some countries in Latin America have already taken first steps towards green fiscal reforms. This outlook article provides an overview of the major challenges for the successful implementation of such reforms and discusses how they could be overcome.

Ethical problems encountered by mental health practitioners working with deaf clients are often complex and involve issues not fully addressed in professional codes of ethics. A principles-based ethical reasoning process can assist in resolving many of these ethical concerns. Principles such as beneficence, nonmaleficence, autonomy, fairness, integrity, and respect are found in the ethical codes of many disciplines; these can also create a common language or reference point when professionals from different fields attempt to deal with shared problems. This article discusses some applications of these principles in working with deaf individuals and proposes an ethical decision-making process that can provide a framework for ethical reasoning in thinking through complex problems.

The role of CT in evaluating patients with small bowel obstruction (SBO) has been extensively described in the current literature. We present the CT findings of SBO due to a phytobezoar, afterwards surgically confirmed, in 5 men and 1 woman (aged 32-89 years) out of 95 patients diagnosed by CT as having SBO in a 44-month period. These six patients underwent abdominal CT prior to operation and the CT findings were retrospectively reviewed. All six patients presented with clinical symptoms and signs of SBO; three of them had undergone gastric surgery 13, 17, and 22 years earlier, respectively. In all six cases, CT showed an ovoid intraluminal mass, 3 x 5 cm in size and of a mottled appearance, at the transition zone between dilated and collapsed small bowel loops. This was in contrast to feces-like material (the "small bowel feces sign"), seen within dilated small bowel loops in nine patients with SBO, and was typically longer. As CT is frequently performed for suspected SBO, an ovoid, short intraluminal mottled mass seen at the site of an obstruction may be regarded as a pathognomonic preoperative sign of an obstructing phytobezoar.
